Product Details
Product Introduction:
Our company manufactures belt-driven industrial centrifugal fans, which are core equipment in medium- and low-pressure ventilation, dust removal, and exhaust gas treatment systems. These fans rely on the rotation of a centrifugal impeller to generate centrifugal force, enabling air conveyance, and are widely used in industrial plant ventilation, dust collection and purification, boiler draft, material handling, and exhaust gas treatment applications.

Applicable Scenarios and Selection Recommendations:
Core use cases:
1. Industrial dust collection systems and baghouse dust collectors equipped with induced draft fans
2. Factory ventilation and exhaust gas emissions from workshops
3. Induced and forced draft for boilers and hot-air furnaces
4. Hot-air circulation and exhaust ventilation in paint booths and baking ovens
5. Pneumatic conveying of fine particulate materials
Key considerations for selection:
1. Airflow and static pressure priority: Calculate the system’s total pressure loss based on ductwork resistance and equipment resistance (such as dust collectors), and select fans with a 10–20% margin of safety.
2. Media‑specific selection: Use wear‑resistant impellers for dust‑laden gases, corrosion‑resistant materials for corrosive gases, and high‑temperature‑rated induced draft fans for hot flue gases.
3. Drive type selection: Belt drives are suitable for applications requiring speed regulation and high-temperature conditions, while direct-drive systems offer high efficiency and low maintenance, making them ideal for ambient-temperature applications with medium to low power ratings.
4. Noise Control: For noise-sensitive applications, use silencers and vibration isolators, and prioritize low-speed models.

Cross-flow air curtain machine
The cross‑flow air curtain employs a large‑diameter, slender cross‑flow impeller—also known as a tangential fan—directly driven by a single‑phase motor to generate a wide, planar, high‑velocity airflow. It is installed above or on the side of doorways. The unit features a flat, rectangular profile with a much reduced depth compared to centrifugal models, allowing it to seamlessly integrate into various ceiling designs. It is particularly well suited for spaces with limited headroom and where aesthetics and quiet operation are paramount, such as shopping malls, supermarkets, restaurants, office buildings, banks, hospitals, and residential garages.
Our company’s surface-type coolers are among the core heat-exchange devices in air-conditioning and ventilation systems. They are primarily used to cool and dehumidify air, and can also be switched to hot-water or steam mode during winter to provide air heating. By utilizing a refrigerant (such as chilled water, refrigerant, or brine) or a heat-transfer medium (such as hot water or steam) flowing inside the tubes, these units facilitate forced‑convection heat exchange with the air flowing outside the tubes, thereby regulating air temperature and humidity. As the central heat-exchange components of chiller units, fresh-air handling units, fan coil units, and other equipment, they offer high heat-exchange efficiency, flexible installation, and broad compatibility.
The ceiling‑mounted fresh air ventilator (ceiling‑type air handling unit) is a central air‑conditioning terminal unit that integrates fresh air exchange, air temperature and humidity control, air filtration and purification, and energy recovery. The unit features a concealed ceiling‑mount installation, suspended within the building’s suspended ceiling. It utilizes chilled water or hot water piping to provide cooling and heating, while simultaneously exhausting indoor stale air and supplying filtered outdoor fresh air. This system not only enhances indoor air quality in enclosed spaces but also regulates air temperature through heat‑exchanger coils, offering both ventilation and central air‑conditioning functions. It delivers energy savings, minimizes floor space occupation, and is widely suited for integration into fresh air systems in commercial, industrial, and large public buildings.
Our company’s Q‑type air heater is an industrial‑grade, forced‑convection heating unit that uses water or steam as the heat transfer medium. It is specifically designed for large‑space applications such as factory and mine workshops, warehouses, large buildings, and drying rooms. The equipment consists of a fan, an electric motor, and a steel finned‑tube radiator integrated into a single unit. Performance tests have demonstrated its stable and reliable operation. By combining “steam heat exchange with forced air supply,” it rapidly heats the air, delivering highly efficient heating and making it one of the mainstream solutions for heating high‑ceiling spaces.
